Job Description:

Are you a curious and motivated engineer looking to help develop state-of-the-art autonomous aircraft? Are you eager to apply your engineering fundamentals to real hardware while learning from experienced teammates? Do you want to work alongside mission-driven and values-focused people? Shield AI may be the place for you.

As a Mechanical Engineer on the Mechanisms team, you will contribute to the design, development, and integration of mechanical systems for Shield AI’s autonomous aircraft. Your work may include a focus on gearbox development and integration, including gears, shafts, bearings, housings, lubrication systems, and related interfaces.

You will complete well-defined engineering tasks with guidance from experienced engineers and collaborate with internal and external partners to design, prototype, test, and release hardware. This role offers the opportunity to build practical experience across the product-development lifecycle while helping the team achieve its performance, schedule, and reliability goals.

What you'll do:

Support the design and integration of mechanical mechanisms for autonomous aircraft, potentially including gearboxes and other power-transmission systems

Create and update 3D CAD models, engineering drawings, bills of materials, and interface documentation

Complete defined design tasks involving component sizing, material selection, tolerance analysis, and mechanical packaging

Perform foundational structural, kinematic, and machine-design calculations with guidance from senior engineers

Assist with preliminary finite element analysis and document assumptions, methods, and results

Support the selection and integration of gears, bearings, shafts, splines, seals, fasteners, and lubrication components

Help build, inspect, test, and iterate prototype hardware for functionality, performance, and reliability

Support pre-production builds, aircraft integration, and ground and flight testing

Investigate well-defined technical issues, document findings, and contribute to root-cause and corrective-action activities

Collaborate with mechanical, propulsion, electrical, avionics, flight-controls, manufacturing, and test teams

Follow established engineering, configuration-management, and product-release processes

Develop plans for assigned tasks, communicate progress and risks, and incorporate feedback from teammates

Required qualifications:

0-1 years of related experience with a bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related technical field, or equivalent work experience

Understanding of fundamental mechanical engineering principles, including statics, dynamics, mechanics of materials, materials science, and machine design

Academic, internship, student-team, research, or project experience using 3D CAD software

Ability to create or interpret basic engineering drawings

Familiarity with dimensional tolerancing and GD&T fundamentals

Ability to perform foundational engineering calculations and clearly document assumptions and results

Hands-on interest in designing, building, integrating, or testing mechanical hardware

Strong problem-solving, organization, documentation, and communication skills

Ability to complete well-defined engineering tasks with guidance from peers and managers

Ability to collaborate effectively, accept feedback, and work in a fast-paced environment with evolving priorities

A demonstrated record of working hard, being trustworthy, holding yourself to high standards, and being kind to others

Ability to obtain an S//SAR-level security clearance is desired

Preferred qualifications:

Internship, student-team, research, or project experience involving aircraft, UAVs, robotics, automotive systems, or other mechanical products

Coursework or project experience related to gearboxes, gearing, bearings, shafts, splines, seals, lubrication, or rotating machinery

Familiarity with gear geometry, gear-train calculations, bearing selection, or mechanical power transmission

Experience with NX or a similar production CAD platform

Exposure to tolerance stack-ups, mechanical fits, and GD&T application

Exposure to finite element analysis, including static, modal, buckling, or fatigue analysis

Familiarity with MATLAB, Python, or other engineering analysis tools

Hands-on machine-shop, mechanic, fabrication, assembly, or inspection experience through professional, academic, or hobby activities

Exposure to FMEA, design of experiments, root-cause analysis, or reliability testing

Familiarity with additive manufacturing, machining, casting, forging, or other mechanical manufacturing processes

Exposure to RTCA DO-160, MIL-STD-810, structural testing, vibration testing, or mechanism testing

Ability to thrive in startup, R&D, or defense-innovation environments
